What Makes Windows Energy Efficient in Passive Houses


Windows are an essential, be it for conventional or new age energy efficient homes which are based on reverse living or passive building concepts. Windows have been incorporated into building designs as a primary factor for allowing in natural energies. More number of windows will mean lesser expenditure on cooling or heating, which at the same time adds to the energy efficiency of the home. Modern window structures are built to be made more energy efficient. Their thermal performance is determined by the elements with which they are built.

Frame and channels

Considering the number of homeowners emphasising on reverse living concepts, manufacturers are seen focussing more on energy efficient framing materials which may majorly include wood and vinyl structures. Vinyl windows are extremely low on maintenance. Meanwhile they are excellently crafted to add to the overall energy efficiency of the house. Vinyl frames offer outstanding thermal insulation. Some of them come with several air chambers in order to add to the thermal performance of the structure.

Even wood frames are excellent as they offer maximum insulation value.

Eco-friendly glass


You can ask an Energy Efficient Home Builder in Melbourne about eco-friendly glass panes. These are mostly referred to as Low-E glass as they have a special coating which helps reflect infrared light to prevent temperature transference. Also, “Low-E” glass is useful in reflecting the UV rays which may cause interior paints and colours on furnishing to fade away with time. 
Weather stripping


Here is a key element adding to energy efficiency of a house. It prevents air leakage and prepares the house for added energy efficiency.

Gas Fills

Air known as “poor conductor” is a considerable choice for making windows eco-friendly. Did you know the air which lay trapped in between glass panes can work as insulator? Modern windows come with adequate space where krypton and argon gas are injected between glass panes. Since these gases are heavier by nature, they are likely to offer better insulation.

Spacers

Modern windows will feature spacers installed in windows. They are fitted to where the glass is sealed with the frame. Some of them come in single units offering structural integrity while enhancing thermal performance. The spacers provide insulation to edges of glass panes. These are considered especially for passive building concepts.

When thinking of window installations especially for a home based on reverse living its important you consider these few aspects to make your home energy efficient.
